Functional hallux braces

The invention relates to a functional hallux brace for correcting the malalignment of the hallux valgus <X malalignment the big toe of the foot), with a corrective brace on the big toe.

After a relaxation of the muscles and ligaments supporting the arches of the foot, it is known to occur in many people a lowering of the longitudinal and transverse arches of the foot. In addition to a flat foot, this also results in it at the same time often a splayfoot, which leads to a widening of the forefoot.

Since today every ready-made shoe is usually one after has a more or less pointed shape at the front, arches lead to a narrowing of the toes. In particular the big toe, which is one of the most important pillars of load on the foot, is moved sideways and on the Longitudinal axis of the foot in relation to an X-misalignment with pivot point in the metatarsophalangeal joint of the big toe.

As is well known, this then leads to wear the metatarsophalangeal joint of the big toe, the arthrosis. In addition, they form on the inside of the base joint Bone growths with painful covering of the bursa. These changes lead to persistent pruning and in the affected individuals Foot pain, which is often completely incapable of annoying the foot do.

Often the symptoms described can only be remedied surgically. But it has also become known to carry out a treatment with a hallux brace, a correction brace that attacks the big toe includes.

In a known arrangement, a metal corrective clasp is placed on the side of the foot (on the big toe side) attached, which has a loop at its front end into which the big toe is guided. Through the The big toe is forcibly brought into a corrected position by pulling it in the direction of the loop adjacent toes are kept away.

However, this solution has the disadvantage that the hallux braces can only be worn at night while it is not

it is possible to place the corrective brace on the foot if the person concerned wears shoes during the day.

The well-known Hallux-Spang ^ is treatment-wise the approach, a registration of the deformity of the Hallux valgus (X-misalignment of the big toe) * pamit can be an improvement in principle Achieve, but there are other approaches to treatment, namely stabilization of the movements in the changed and worn metatarsophalangeal joint, a follow-up treatment by splinting after an operation and, in particular, a correction with an erection of the transverse vault.

This is where the invention comes into play, which is based on the task of creating a functional hallux brace, which can also be worn in the shoe, and which also require a correction with straightening the transverse arch enables.

The solution to this problem is given in the preamble of claim 1 mentioned hallux brace, characterized in that the correction brace runs along the sole of the foot.

In a new way , the correction brace is located below the foot, ie the sides of the foot remain free. This leads to the advantage that the hallux brace can easily be used even with a foot in the shoe.

Another advantage of splinting from the sole of the foot results from the fact that neither bursa nor irritated skin regions are present here. Finally, the invention enables the arrangement of the correction clasp along the sole of the foot in an advantageous manner also a arch support, because in practical embodiment of the invention, the correction clasp is guided in a loop of a comprehensive foot Vorfußbandage which is slipped over snugly on the foot and fußsohlenwärt s a Contains padded loop compartment. The elastic forefoot bandage provides arch support.

Within the loop, the correction clasp is connected at a pivot point to a support plate, and a fastening tape engages at the rear end of the correction clasp.

When moving the rear end of the corrective clasp

by more or less tight guidance of the fastener tape, the front one moves the larger one End in the opposite direction, and thus it is possible to make a desired correction position for the To adjust the big toe, i.e. the corrective position can be adapted in an advantageous manner to the healing process.

The invention can be used with advantage even if the metatarsophalangeal joint of the big toe is completely worn Big toe deformity (Hallux rigidus) apply what to the new feature of the soles of the feet Corrective clasp is due, with the corrective clasp engaging the big toe from below.

Other expedient refinements and advantageous developments of the invention are set out in the subclaims and to be taken from the drawing.

The invention is explained in more detail below with reference to the exemplary embodiment shown in the drawing. Show it:

the forefoot bandage 32 is only shown in phantom y in FIG. 3, while FIG. 4 is a cross-sectional view

along the section line A-A, the forefoot bandage 32 can be clearly seen.

On the lower side of the forefoot bandage 32 there is a loop 34 in which the correction clasp 20 is performed. Furthermore, a support plate 30 is located in the forefoot bandage within the lower area 32, and the correction clasp 20 is pivotably connected to the support plate 30 at the pivot point 28 .

At the upper end, the correction clasp 20 has an approximately U-shaped receiving zone 22 for embedding the big toe 14 of the foot 10. On the one side facing the wide toes 16, the Receiving zone 22 has a supporting wall 24 which is adapted to the shape of the big toe 14.

The correction clasp 20 is at its rear end connected to a closure tape 26, which is designed as a Velcro tape and together with one on the Forefoot bandage 32 externally attached closure part 36 forms a Velcro fastener.

The connection of the correction clasp 20 to the support plate 30 in the pivot point 28 allows a lever-like movement of the correction clasp 20. When the lower end according to Fig. 3 is moved in the direction of arrow C, the receiving zone 22 migrates in the opposite direction, as indicated by the arrow D. By the pulling force of the fastener tape 26 which, as shown in FIG. 2, spans the foot and with the fastener part 36 is connected, so the position of the receiving zone 22 - and thus the compulsory storage the big toe 14 - affect. This makes it possible to make a correction according to the respective needs or according to the present healing process. The loop 34 is chosen so large that the corresponding displacements of the correction clasp relative to the stationary support plate 30 are possible. In Fig. 2, the arrow B indicates the direction in which the big toe 14 by means of the correction clasp 20 can be held or influenced.

Since the correction brace 20 is padded inside the loop 34 or inside the forefoot bandage 32, pressure problems are avoided. In addition to its corrective effect, it immobilizes over the sole of the foot the big toe joint running correction bar a certain amount Immobilization of the painfully altered joint.

The new hallux brace 18 described so far is combined all possibilities of arch support and simultaneous toe correction. The following indications are possible: a) splayfoot problems with the beginning of the crooked toe; b) Arch support with splayfoot and fully developed Hallux valgus; c) Hallux rigidus (complete wear and tear of the metatarsophalangeal joint without the big toe misalignment); d) postoperatively after corrective surgery.

The special features of the new Hallux braces 18, which are achieved by slipping over the elastic Forefoot bandage 32 is attached to the foot 10 are: a) Correction from the sole of the foot downwards (thus also wearable in the shoe); b) no formation of bursae and exostoses (bone growths on the bone near the joint); c) stepless reinforcement of the correction through increased Tension of the loop or the forefoot bandage; d) Combination of arch erection and correction of toe misalignment; e) Possibility of constant inquiries (in relation to known arrangements that are either night or Act daily correction clasp); f) dosed guidance of the worn big toe joint, without this to immobilize.

The support plate 30 and the correction clasp 20 exist made of plastic.
